He plans to sign a plea deal that will lock him up for 20 years, his lawyers said. He could be on supervised release after prison and will have to register as a sex offender, according to court documents.

Beasley was arrested April 1 after police spotted him and the underage student half-naked in a parked car in Deerfield Beach. The pair admitted to performing oral sex on each other.

The teacher, of Plantation, told police he had been having sex with the girl since Valentine's Day.

Beasley told police he and the girl acted inappropriately during school hours three times.

The couple exchanged naked pictures and Beasley sent a video of him masturbating, FBI agents and Broward Sheriff's deputies discovered. The pair also shared graphic texts.

"I want to feel you. lnside and out. Not want. Need. l require physical intimacy with you. Kissing you feels as essential as breathing," Beasley wrote in a text.

Beasley "still cares for the girl," Gelety said. A doctor called the former teacher a "wandering romantic."

Beasley was placed on unpaid administrative leave after his arrest.

The girl's parents are suing Beasley, the school, Zion Lutheran church and affiliated organizations and officials.
